COP8SBR9KMT8

Overview

The COP8SBR9KMT8 is an obsolete 8-bit microcontroller from the COP8™ 8S series, manufactured by National Semiconductor. It features a COP8 core operating at a maximum clock frequency of 20 MHz. The device integrates 32KB (32K x 8) of FLASH program memory and 1KB of RAM. It utilizes a 56-TFSOP package with dimensions of 0.240 inches (6.10mm) width and 0.9 mm height. Connectivity options include Microwire/Plus (SPI) and USART interfaces.

Feature Summary

• High-performance 8-bit CPU core for efficient processing
• Low-power operation capabilities
• Integrated FLASH program memory with virtual EEPROM functionality

Applications

• Industrial electronics control systems
• Consumer electronics devices
• General-purpose embedded applications requiring low power

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm RoHS status, which may be non-compliant depending on production batch. Ensure compatibility with existing design constraints before procurement due to end-of-life status.

Selection Notes

Select this part only if legacy support for the COP8 architecture is required. Consider modern equivalents if new designs are initiated. Verify interface compatibility with SPI and USART requirements. Check package pinout alignment with current PCB layouts.

Part Context

Part of the COP8 family, specifically the 8S variant. Manufactured by National Semiconductor, now part of Texas Instruments. Designed for cost-sensitive, low-power applications. Obsolete status limits long-term supply chain stability.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult Microchip USA or National Semiconductor archives for potential cross-references. Evaluate architectural differences when selecting alternatives.
